Greetings All,

I’m starting a project here at my home. I am replacing a beat-up thirty-year-old swing door on the garage with a new Clopay 15’X 7’ HDGL roll-up door. The rough opening is fifteen feet-two inches wide and seven feet tall. I am following Clopay’s “Prepairing the Opening” document found at –

http://www.clopaydoor.com/DAM-Mirror/PDF/manuals/singles/Preparing-the-Opening.pdf

However, the current side-jambs of the opening are at 15’2” apart, as well as overlap the inside garage wall by almost two inches. I want to follow Clopay’s document by putting a 2X6 jamb on the inside garage wall. Nailed directly to the 2x4 framing. But I do NOT want to butt the 2” side up against the back of the 2x6 opening jamb. I want the inside wall jamb to overlap the 2x6 opening jamb as illustrated in Clopay's document.

Fortunately (but unfortunately overall), the siding as well as the 2x4 trim on the outside front of my garage is very weather worn and near rotted from 10 years of neglect. So I want to reposition the 2x6 opening jamb two inches forward towards the front of the house to flush up the joint with the inside framing and the'about-to-be-installed' wall jamb. I want to replace the siding and house trim out front and basically rebuild my whole garage door rough opening and make it 15 feet instead of the fifteen foot-two inches.

My current frame is as follows: (looking at the left inside of opening) A 2x4 frame from floor to ceiling- nailed to that is a 2x4 from floor to garage opening header-nailed to that is about a ½” piece of filler-wood I guess and then nailed to that is the 2x6 that overlaps approx. 2 inches on each side (outside and inside)

So, my question is this –

What are my best options to create a new rough door opening that is EXACTLY 15’ x 7’? ( closing the width 2”) .While also framing the inside walls with 2x6 as shown in the Clopay document? I guess my main reason for wanting to copy the document so exactly is I don’t want to screw in the vertical track rails and screw into the seam of a pair of two-bys. And it also just looks cleaner. If the seam is on the rough-opening side of the jamb then it will be covered with any stop molding / weather-strip. But this will throw the front of the 2x6 opening jamb two inches further out front, creating a weird seam with the adjacent trim outside.

I need some good professional advice.

I’m not sure I explained myself very well. You can probably tell I am a rank amateur at this as this is my biggest DIY project of only a few around the house. So, since they say a picture is worth a thousand words - here is a picture of the jambs…and inside wall.

Thank you all in advance,

p.s. As you can see in the photos, the outside header trim is just as useless. It doesnt even span all the way to the outside vertical trim! ( You can zoom those in quite a bit)
